Sodium Azide Poisoning

Annals of Internal Medicine, 1975
Excerpt To the editor: Since we (RS, RG) were responsible for the suggestion that the therapeutic induction of methemoglobinemia might be of value in acute azide poisoning (1, 2), we are naturally ...

A microbiological assay for sodium azide

Analytical Biochemistry, 1980
Abstract A reproducible and sensitive method is presented for quantitating sodium azide (NaN 3 ) that exploits the fact that NaN 3 inhibits Escherichia coli RNA synthesis. A linear correlation is observed between incorporation of [ 3 H]uridine into a trichloroacetic acid-precipitable form and NaN 3 concentration over a 31- to 2000-μg range of ...

Polymerization of nitrogen in sodium azide

The Journal of Chemical Physics, 2004
The high-pressure behavior of nitrogen in NaN3 was studied to 160 GPa at 120–3300 K using Raman spectroscopy, electrical conductivity, laser heating, and shear deformation methods. Nitrogen in sodium azide is in a molecularlike form; azide ions N3− are straight chains of three atoms linked with covalent bonds and weakly interact with each other.

Suicidal sodium azide ingestion

Annals of Emergency Medicine, 1987
Sodium azide (NaN3) is a highly reactive, toxic, widely used chemical. Although industrial exposure is common, fatal ingestion is rare. We describe the case of a 30-year-old man who ingested 15 to 20 g of sodium azide. He became comatose within two hours and eventually expired from a combination of acidosis, respiratory depression, and ventricular ...

Thermoluminescence of sodium azide

Journal of Physics C: Solid State Physics, 1969
Thermoluminescence in sodium azide has been produced in the temperature range 15-300 °K by x-ray or gamma-ray irradiation. By analysis of the individual glow peaks at low heating rates, it is possible to characterize these peaks from the values of E (activation energy) and S (the pre-exponential factor).

ChemInform Abstract: THE PHASE TRANSITION IN SODIUM AZIDE

Chemischer Informationsdienst, 1983
Sodium azide undergoes a transition from a high-temperature rhombohedral phase to a low-temperature monoclinic phase at 292.2 K. Results of x-ray diffraction studies of the low-temperature phase are reported which indicate that the transition is of the elastic type with the order parameter corresponding to a linear combination of the strains e13 and ...

Solubility of Sodium Azide and Alpha-Lead Azide.

Journal of Chemical & Engineering Data, 1966
The solubility of sodium azide was determined in water and in 40, 60, 80, and 95.5% ethanol-water mixtures, respectively. The solubilities were first determined by a synthetic method (9) which involved the preparation of a solution of known composition, the saturation point of which was determined by varying the temperature.

Thermal decomposition of sodium azide

Thermochimica Acta, 1977
The thermal decomposition of sodium azide has been investigated in the temperature range 240–365°C. Three values for the activation energy, 37.0, 59.0 and 14 kcal mol−1 have been obtained depending on the temperature range of study. The mechanism of decomposition seems to involve excited azide ions (through internal conversion) and excitations.

The reaction of tetrafluorohydrazine with sodium azide

Journal of Inorganic and Nuclear Chemistry, 1966
Abstract The reaction of tetrafluorohydrazine with sodium azide at 45–85° produces nitrogen trifluoride, nitrogen and sodium fluoride. The yield of nitrogen trifluoride is pressure dependent and increases almost linearly from 30 per cent at 3 atm to 70 per cent at 8·5 atm.
